Large Breed puppies require a different nutritional mix than medium/mini breed puppies because of their rapid rate of growth. While protein levels need to be high, fat levels along with Phosphorus and Calcium quantities need to be lower than a regular puppy recipe to avoid developmental orthopedic diseases like hip dysplasia. High amounts of chondroitin and glucosamine play an important role too, as they boost cartilage growth and help prevent joint related diseases. Our AMBROSIA Growth for Large Breeds – Fresh Chicken & Salmon recipe is suitable for all puppies of large breeds and can be used also for medium breed puppies above 6 months of age
